Reconstruction of Scalp Defects using Bilobed Flap

Kim, Jong Gu; Yang, Ho Jik

Abstract

The bilobed flap is often used when the primary closure of a skin defect is difficult. We applied a simple and rational method to design a bilobed flap for closure of scalp defect that reconstruction was comparatively difficult. In our method, two triangle flaps are designed; the angle of the first flap is three-fourths the angle of a rhombus at the defect site, and the angle of the second flap is also three-fourth that of the first flap. We applied it to five patients with scalp defect and obtained favorable result. The location of the defect was the parietal region in two cases. the occipital region in two cases. the frontal region in one case. We found that the alopecia by scar formation could be minimized with the designed bilobed flap. The suture line, being "Z" shape, was unnoticeable due to hair line stream. There are several advantages of this method for use in reconstruction of scalp defect such as, easy design and elevation of the flap and short operation time.
